Dynamic Process Modeling of Electric Arc Furnace Steelmaking Using Direct Reduced Iron Charges: Focusing on Dephosphorization

Metals
The use of direct reduced iron (DRI) in electric arc furnace (EAF) steelmaking has grown in popularity, yet dephosphorization, as a special concern because of high phosphorous levels, is yet to be fully understood.
